But Saha, who enjoyed a trophy-laden four-year spell at United, believes Martial will bring a different dimension to United’s attack and has backed him to torment unsuspecting Premier League defenders.

“He’s got that speed, that power, he’s got that youth in him so he’ll surprise a lot of defenders because they don’t know him,” Saha said.

“It’s a great asset for Manchester United and that’s what they needed because up front they lack speed sometimes.

“In France we call him the next Thierry Henry because he can play left or right and he’s got a great ability with the ball.

“He can take on three, four players with ease, there is no problem. At the same time, the new generation have no fear.

“He’s got such an ability that he can win trophies for Manchester United I believe that, but I don’t want to put too much pressure on him.”

Martial could be in line to make his Manchester United debut this weekend, with Liverpool the visitors to Old Trafford on Saturday Night Football.
